MACHINE FO R GAGING AND MARKING LEATHER.

SPECIFICATION forming part of Letters Patent No. 276,782, dated May 1, 1883,

Application filed September 9, 1882. (No model.)

To all whom it may concern: I

Be it known that I, CHRISTIAN DAivcEL, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Machines for Gaging and Marking Leather or other Materials, of which the following is a specification.

- This invention relates to a machine which is composed of a mechanism for gaging the thickness of the material to be marked, and of marking devices the action of which is governed by the gaging mechanism, so that the variations in the thickness of the material passing through the gaging mechanism are indicated bythe marks produced on said material by the marking devices.

This invention is illustrated in the accompanying drawings, in which Figure 1 represents a sectional front view. Fig. 2 is a sectional end view, looking in the direction of arrow 1', Fig. 1. Fig. 3 is a partial end view, looking in the direction of arrow 2, Fig. 1. Fig. 4 is a transverse section of the type-carryinggage-roller, showing also the impressionroller in the plane or as, Fig. 1.

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a frame composed of two standards, a a, which are united by traverses b c. The standards a a are provided with slots d for the reception of the boxes 0 c f f, which form the bearings for the gage-rollers B O. The boxes c c of the upper gage-roller, B, abut against the upper ends of the slots d, so that they cannot rise; but the boxes f f of the lower gage-roller, 0, rest upon a box, D, the ends of which are guided in the slots (2 and rest upon springs E, situated in said; slots.

To the bar D is secured by a pivot, g, a curved lever, F, the upper end of which carries the box 71., fitted into a guide-slot, t, and embracing a pin, j, which extends from a slide, G. This slide isfitted upon the upper traverse, b, so that it can move thereon in the direction of its length; but it is prevented from turning round by a feather key or equivalent device. The leverF has its fulcrum on a pivot, k, which has its bearings in lugs l l, rising from the lowertraverse, c. If the lower gageroller is depressed, the lever F turns on its fulmight be substituted which will readily sug- I gest itself to an ordinary mechanic, and I do not wish to be confined to thepreciso mechanism shown in the drawings.

In the slide G is mounted the impressionroller H, which acts upon the types 1.. These types'are fitted into holes which extend through the upper gage-roller, Fig. 4, and each of them is provided with a recess, 122, into which extends the tip of a screw, it, which is tapped into the. gage-roller in a direction at right angles to the type. The types therefore are free to move in the direction of their length as far as the recesses m and the screw it will perunit.

A rotary motion is imparted to the gage: rollers B O by means of a shaft, I, which has its bearings in the standards a a of the frame A, and is geared together with the lower gageroller, 0, by cog-wheels o p, Fig. 2, and 'with the upper gage-roller, B, by cog-wheels q r s, Fig. 3, so that the two rollers'will revolve in opposite directions.

By referring to Fig. 4H: will be seen that the types aresomewhat longerthan the diameter of the gage-roller B, and they extend through said roller in different directions, so that im-' pressions produced by them will not come too close together. On the faces of the types are figures or other characters or marks.

In order to show the advantage of my machine, I will now describe its operation when used for gaging and marking a piece of leather intended to be cut up into soles for boots or shoes.

In the manufacture of boots or shoes it is customary to use soles of uniform thickness for each case of boots or shoes, and the manufacturer gives his order for soles of the desired thickness. If the thickness desired is not marked on the leather, the cutter loses much time in finding out the thickness while cutting the desired soles. It will therefore be readily seen that the operation of cutting out the soles is greatly facilitated it the leather is provided with marks indicating its varying thickness. The marks which I have selected, and

ICC

2 averse which are engraved orotherwise produced in the faces of the types, are the figures 1, 1%, 2, 2%, and so on, said numbers indicating the different thickness of soles which may be required for the different cases of boots and shoes. When the gage-rollers B G revolve and a piece of leather is passed through between them the lower roller descends when the thickness of the leather increases, and it ascends when the thickness of the leather decreases, and at the same time, by the action of the lever F, the slide G is adjusted so as to carry the impression-roller H over the type which carries the figure indicating the thickness of the leather at that point. As this type passes beneath the impression-roller an impression is produced upon the leather, indicating its thick ness'at that point, and so on throughout its entire length. By observing the marks or figures on the leather the cutter is enabled to out out soles of the required thickness, and the operation of cutting up a piece of leather for soles of various thicknesses can be carried on with a saving in time and in stock.

Of course my machine can be used for gaging and marking other materials besides leather.

before described, of the two gage-rollers, one

of which is mounted in movable bearings, the

impression-roller, which is movable in the direction of the length of the gage-rollers, mechanism for transmitting motion from the movable hearings to the impression-roller, and the types mounted in the gage-roller with fixed bearin gs.

2. The combination, substantially as hereinbefore described, of the two gage-rollers, one of which is mounted in movable bearings, a lever which is actuated by the movable bearings, an impression-roller mounted in a slide which is actuated by said lever, and a series of types mounted in the gage-roller with fixed bearings.

3. The combination, substantially as hereinbefore described, of the two gage-rollers, one of which is mounted in movable bearings, the bar D, supporting said movable bearings, the lever F, pivoted to said bar and having its fulcrum on a fixed pin, the slide G, connected to said lever, the impression-roller H, mounted in said slide, and. the types t, mounted in the gage-roller with fixed bearings.

4. The method, substantially as described, of producing on leather or other material marks for indicating its varying thickness by the action of a series of types and of mechanism for selecting and actuating said types according to the varying thickness of the material to be marked. I

5. The combination, substantially as hereinbefore described, of a mechanism for gaging the thickness of the material to be marked with marking devices the action of which is governed by the gaging mechanism.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
